Abstract: We consider a 2D numeric simulation of the liquid-solid transition in an Al-Mg alloy. The liquid melt is contained in an axisymmetric rectangular enclosure with isothermal walls. The heat transfer is modeled using the Fluent V.6.3.26 code. In the unsteady state of the process, free convective fluid flows are seen as two contra-rotating swirls. This movement is driven by the important temperature gradients generated in the liquid region. When the steady state is established (liquid-solid equilibrium), the velocities determining the convective flows are cancelled. The solidification proceeds then by a purely conductive mode. The interface shape is determined during the unsteady state by the convective flows, and then, remains unchanged until the solidification process is achieved.
